Wheels, ofwhich the following is a 'speci fication.

My invention relates to that class of wheels in which a sheet metal disk or plate having rim, hub and web or spoke parts all of one plate of metal is employed in the construction of the wheel either alone or in combination with a separate rim or felly engaging the edge or edges of the disk or disks used in the construction.

' 'Theobject of the invention is to produce a wheel of the above general character hav ing great strength, simplicity and cheapness of construction, together Wltll great resistj I edge, is preferably formed, as indicated,

ance to load and torsional strains.

A further object is to, provide a construc-.

tion of disk itself that may be conveniently and cheaply used in the construction of metal wheels of the disk'type by employing one'or more of said disks in 'any'deslredway and which disk shall embody in its constructionmeans for strengthening or reinforcing the wheel against the effects of torsional strains.

To these ends my invention consists in the construction bfdisk or plate embodying strengthening tongues or struts as hereinafter described. 1

The invention further consists in the manner of combining said disk with the rim wheel embodying my invention and having invention.

my improved form of disk embodied in its construction.

Fi 2 is a cross-section of said wheel on.

METAL WHEEL.

disk or plate, 2 the rim or edge part arid?) the hub portion perforated as shown for the.

Specification of Letters Patent. Patented Mi reception of the axle and bearingboxes, at wh1'ch part 3 said disk may, in the construc-- tion of the wheel, be reinforced by a suitable preferred construction of wheel embodying my invention, is provided with the: inwardly turned flanges 5 at its edges. My invention, however, is not limited to this particular construction of rim but may be realized with other forms of metal rim with which, my improvedconstruction of disk is suitably combined. i

The edge of the the rim, engages the inner surface of said rim to receivethe loadand, at the engaging with the wings or ears 6 forming a transversely extending .bent edgeof the disk.

These ears preferably extend in opposite directions from the planeof the disk and serve for attachment of the rim to the disk by unions made between them and the inner surface of the disk in any desiredwa'y as by disk when combined with" Way of embodying my improved disk ,therea circumferential line intermediate theedges of the rim. The disk maybe located centhus giving a larger overhang on one side in, said diskre'ceives the rim on its edge on than on the other which is sometimes de I sired. The said wings or ears areindicated in Fig. 3, the line of bendbeing shown by the dotted line 7. i i i 8 indicates metal tongues cut out of the body of-th'e .disk or plate integral therewith and bentto one side of the plane of the disk to engage the rim at their freeends out of the general plane of'the disk and thereby] I.

form struts or effecting practically'a dishingof the wheel, whereby resistanbe to torsionalst'rains tending to collapse the wheel isresisted. To form a doubledishing the said tongues are bent in opposite directions Y from the planeof the disk, .At their freej 4 ends they engage the rim preferably at or near its edges in any desired way. lVhen the rim is formed with the inwardly turned circumferential edge the tongues may be secured to the inside of the flange by spot welding or otherwise, their extreme ends being bent over if desired, under the inside of the rim as-shown in Fig. 4; and welded thereto. If desired the bent over ends may be dispensed with and the union made with the flange 5 only as indicated in Fig. 2. Ob- I viously a number of thedisks might be employed in the construction of the wheel, the planes of the disks being displaced with relation to one another axially with the wheel.

The new form of disk, however, lends itself particularly to use in making up a wheel of effective strength and cheaply by. employing but one disk.

If desired the struts 8 may be twisted at any point of their length so that their edges are presented to the side of the wheel rather than their flat sides as shown.

lVhat I claim as my invention is 1. In a wheel of the character described, a

sheet metal disk having its edge bent over at U edge in the plane of the disk with said rim to sustain the load, said disk having also tongues bent in opposite directions from the plane of the disk at points approaching the hub and connected at their free ends to the rim at its edges. p

3. In a Wheel of the character described, the combination with a rim having an inwardly turned flange at each edge and a sheet metal disk disposed with the plane of the disk intermediate the edges of the rim, said disk being engaged with the inner surface of the rim in the vertical plane of the disk to receive and support the load in said plane, said disk being also provided with transversely bent tongues bent from "the plane of the disk at points near the hub and connected at their free ends to said flanges as and for the purpose described.

4. In a wheel of the character described, the combination with a metal rim having inwardly turned flanges at its edges, adisk having a transversely extending bent edge engaged with the inner surface of the rim and provided with tongues bent in opposite directions from the plane of the disk and secured at their free ends to the inwardly turned flanges.
